ヨサファット研究室の研究・教育用の設備

We always try to serve a complete and satisfied facilities for Microwave Remote Sensing research and study by installing high precision instruments for simulation, fabrication, measurement and applications for National-wide and International join researchs. We always aim higher science and technology to realize some microwave sensors for unmanned aerial vehicle and microsatellites. This satellites will be employed to investigate the relationship between ionospheric phenomenons and global land deformation. We hope could reduce the victim by earthquake by monitoring the earthquake precursor by using our microsatellites. If you plan to hold a joint national or international research with our laboratory, please don’t be hesitate to contact Prof. Josaphat.

Josaphat Microwave Remote Sensing Laboratory (JMRSL) operates satellite ground station in frequency of S band for command and telemetry, and X band for data mission downlink with diameter of 3.5 m. This facility was built by the support of The Japan Ministry of Education and Technology and Chiba University (PI : Prof Josaphat Tetuko Sri Sumantyo, FY2013-FY2016)

Our anechoic chamber could operate in frequency range of 1 to 40 GHz (microwave) and size L6.6 x W4.0 x H2.4m. You could employ this facilities for radio wave environmental test, scattering experiment, antenna and microwave instruments including spaceborne instrument etc.
This facility was built by the support of The Japan Society for the Promotion of Science (JSPS) Grant-in-Aid for Scientific Research / Kagakukenkyuhi 2007 – Young Scientist (A) (No. 19686025), Development of circularly polarized Synthetic Aperture Radar to generate high precision image (PI : Prof Josaphat Tetuko Sri Sumantyo, FY2007-FY2009)

Large Scale Unmanned Aerial Vehicle (JX Series) （大型無人航空機（JXシリーズ）
Josaphat Laboratory develops Josaphat Laboratory Experimental Unmanned Aerial Vehicle (UAV). We plan to develop four UAVs in JX Series for ground test of L, C, X and Ku bands UAVs in the future. We already have realized JX-1, and development of JX-2 is in progress. JX-1 and JX-2 will be used for tandem mission of UAV SAR experiment in the near future. This JX series is employed for ground test of several sensors before we install on our microsatellites.
This project is supportted by several research grants, including Japanese Government National Budget (Special Budget for Project) FY 2013, “Integrated Earth Environment Diagnosis Program : Continental Scale Land Deformation Observation using Small Satellite Constellation,” PI: Prof. Josaphat Tetuko Sri Sumantyo, 1 April 2013 – 31 March 2017.
